For a client in the Midwest, our scope of work included the addition of two (2) new 138kV bus tie circuit breakers to split the 138kV main buses into four busses.
We also replaced five (5) existing 138kV breakers with new Siemens 138kV circuit breakers. Several corresponding sets of switches have also been replaced, along with other electrical equipment.
A new Drop In Control Module (DICM) has been installed consisting of a 16’ x 36’ base with a 16’ x 24’ expansion unit. New cable trench design has been required to accommodate new wiring for complete station into new DICM control building.
This project included engineering and design for civil, electrical physical layout, grounding and lightning protection systems. Civil design included design of equipment support steel framing and concrete.
Due to the age and condition of the station, RCM performed 3D scanning to collect accurate and exact data of the existing yard regarding dimensions and overall physical layout. A 3D Point Cloud was used during the design stage to incorporate custom solutions to accommodate new equipment while ensuring constructability and a high safety environment.
An integrated design approach incorporating the use of a 3D model of the station has been utilized to collaborate with our client. Included in this approach is the creation of a 4D model which incorporates the 3D model of the station with the construction schedule as well as the creation of safety animations and work sequence animations.
